hint for all: the code above uses the playfair method, and for PpPP. you know? in playfair every letter is a pair. that's how we can determine the original letter. but, in playfair, double-letters will be angled up left. if there is 1 letter then the letter remains. example: based on key in photo.png => original letter in cipher "K" is "K" but original letter in cipher "Kk" is "Aa". playfair learning reference for beginners -> https://en.wikipedia.org/wiki/Playfair_cipher

Untuk PpPp -> Pp PP (berdasarkan komenku diatas, kalian seharusnya mengerti huruf apa itu)
